| Abstract | Deinococcus geothermalis is resistant to chemical and physical stressors and forms tenuous biofilms in paper industry. The architecture of its biofilms growing on glass and on stainless acid proof steel was studied with confocal laser scanning microscopy and fluorescent lectins and nanobeads as in situ probes. Hydrophobic nanobeads adhered to the biofilms but did not penetrate to biofilm interior. In contrast, the biofilms were readily permeable towards many different lectins. A skeletal network of glycoconjugates, reactive with Dolichos biflorus and Maclura pomifera lectins, was prominent in the space inside the biofilm colony core but absent on the exterior. Cells in the core space of the biofilm were interconnected by a network of adhesion structures, reactive with Amaranthus caudatus lectin but with none of the 65 other tested lectins. The glycoconjugates connecting the individual cells to steel reacted with Phaseolus vulgaris lectin whereas those connecting to glass mainly reacted with A. caudatus lectin. Envelopes of all cells in the D. geothermalis biofilm reacted with several other lectins, with many different specificities. We conclude that numerous different glycoconjugates are involved in the adhesion and biofilm formation of D. geothermalis, possibly contributing its unique survival capacity when exposed to dehydration, biocidal chemicals and other extreme conditions. |
